RADIO COMMUNICATION SYSTEM, BASE TRANSCEIVER STATION, AND EXTENSION DEVICE

摘要

In a wireless communication system, a plurality of base transceiver stations (103) and at least one extension device (106) are connected via an IP network (100) that uses internet protocol. The extension device (106) shares resources of the base transceiver stations (103) by arbitrarily changing a connection relationship between the base transceiver stations (103) and the extension device (106). When a mobile terminal communicates with a core network (101), the extension device (106) uses the resources of one or more of the base transceiver stations (103) according to fluctuation in the amount of traffic.
